Application October 3, 1941,-Serial No. 413,409

6 Claims. "(01. 36-75) women and children to walkthrough puddles of water, slush, mud, etc., without wetting their shoes.

More specifically, the invention proposes a platform attachment which is especially simple in construction, and is adapted to be easily secured to ones shoes, which is light in weight, and functions efficiently, especially as a .war emergency device to save rubber and leather.

The invention proposes that each platform attachment have a plate for engaging against the bottom of a shoe and having certain downwardly projecting support portions at the sole andheel areas of the shoe supporting a sole casing and a heel casing, which in turn support a sole -pad and a heel pad, respectively, for engaging .the

ground. It is proposed that these pads be constructed of cork, or similar-materials.

Still further the invention proposes that the sole pad be of horse shoe construction so as to reduce the weight of the platform attachment and at the same time maintaining treading advantages.

For further comprehension of the. invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a side elevational view of a platform attachment constructed in accordance with this invention and shown applied to a shoe.

Fig. 2 is a plan view of the platform attachment, per se, taken on the line 22 of Fig. 1.

Fig. 3 is a bottom view of Fig. 1 looking in the direction of the line 3-3 thereof.

Fig. 4 is a longitudinal vertical sectional view of the platform attachment shown in Fig. 1.

Fig. 5 is a developed view of the blank used for constructing the plate with the projections, for the platform attachment.

Fig. 6 is a side elevational view of a platform attachment constructed in accordance with a modified form of this invention.

The platform attachment for shoes, in accordance with the form of the invention illustrated 55 port portions I5.

in Figs. 1 to 5, includes a-plate- It for engaging 7 against the bottom of a shoe andhaving a plurality of upwardly projecting prongs I I for gripping the sole I2 and heel I3 of a shoe, such-asthe shoe I4 illustrated in Fig. 1. .The plate III is also provided with a plurality of downwardly projecting support portions I at the sole andheel areas of the shoe. These support portions have out turned bottom ends I6.

A sole casing I1 forsupporting a sole pad I8 I isattached to the outwardly projecting end I6 horseshoe shape, see particularly Fig. 3.

of the downwardly projecting portions I5 which arelocated at the solearea. A heel casing I9 supporting a heel pad- 20 is attached to the outwardly projecting ends I6 of the support portions I 5 which are located at the-heel area.

1 The pads I8 and- ZU-preferablyare constructed of cork-material, though other materials such as felt may be used. The sole casing I8 is of It is formed from hollow material which is open at the bottom and at these points has inturned flanges: 21 which engage complementary shoulders formed on the sides of the pad I8 for firmly holdingthe pad in place. The heel casing- I9 is also of hollow construction open at the bottom and having inturned-edges 22 which engage complementary shoulders formedinthe side of-the heelpad 20.

. Fig. 5 illustrates a blank for constructing the plate and the projecting portions, which are used in the platformattachmentr This blank has a soleand-heel'engagingarea I9 from the edges of which. prongs I I- project, which areadapted to be bent upwards to form the prongs II. Also, the plate 10' has projections I5 which are adapted to be bent downwards to form the downwardly projecting support portions I5.

A strip of covering material 23, in the nature of a felt sole and heel piece or other sheet material, is mounted upon the top of the plate I 9 and is adapted to directly'engage the bottom of the shoe when the attachment is mounted thereon.

In Fig. 6 a modified form of the invention has been disclosed which is similar to the previous form, merely distinguishing in the means by which the platform attachment is attached to a shoe. In accordance with this form of the invention the platform has a plate Ni which is provided only with the downwardly projecting support portions I5. Instead of the upwardly projecting prongs, several leather or other straps 25 are mounted through openings 26 formed in certain ones of the downwardly projecting sup- These straps 25 are provided with the usual buckles 21 by which they may be securely engaged about ones shoe. In other respects this form of the invention is identical to the previous form and like parts are indicated by like reference numerals.

This platform attachment may be used at all times, even in dry weather, for increasing the height of the wearer, also by men who work in mines, quarries, etc. on uneven surfaces and by persons with feet of uneven length, by making one shoe attachment higher than the other.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
